[WTB] - Custom Weather and Rainfall Calendar Excel Spreadsheet Wanted!

I am writing this because I need someone with Excel Spreadsheet experience to design me a custom made Weather Calendar which will list Daily Rainfall, Temperature, Barometirc Pressure etc.
The spreedsheet will need to have 12 pages representing each calendar month and another page or two for the overall averages etc
Obviously on each page it will need to have each or the current months days, and boxes for the person to enter the days temperature, rainfall for that day, etc.
Each time the person enters the days temperature, rainfall etc it will need to average those figures down the bottom of the months cycle.
I also want spaces on this calendar where I can place my website banners, and also hoping that there is no way that the banners cannot be removed by the person who downloads it, but can be updated by myself etc.
I run a rural Australian Website, and I will be offering this calendar for free to my members, who rely on the weather for their industry, i.e. farming.
So the spreadsheet will be aimed at farmers and country people.
Looking to pay $50 - $100 for someone to help me with this.
This calendar is to be designed for me only, and not be onsold, so I want full copyright for it.
I am after a professional person who is preferred to be from a English speaking background, someone who is patient and will work on the spreadsheet until we get it up to my standards.
